hello, i have a flues sxs 20, with 26" barrels, f/f. from the ser # it was made between 22-23. my question is, it has 20 stamped into the water table and an S stamped directly above the 20. the gun has dogs on point engraved on both sides, but obvously isn't a sousa. would the S designate a number 1 special grade?


thanks for any help you can provide,,,,, joe
